摘　　要：针对数据中心光交换阵列切换慢、延时大的技术问题,提出了一种大规模光开光阵列驱动控制电路设计方法。在介绍大规模光开关阵列驱动控制电路原理的基础上,先设计出单路高速、幅度可调光开关控制电路,进而设计了2000路光开关阵列驱动控制电路,并给出了主要芯片的选型依据,最后通过实验验证了设计的正确性。通过创造性地使用2个数字电位器和1个高速开关,实现了高电平和低电平均可调节的驱动控制电路设计,为光开关阵列驱动控制电路的设计提供了参考和借鉴。Aiming at the technical problems of slow switching and large delay of optical switching array in data center,a design method of drive and control circuit for large-scale optical switching array is proposed.On the basis of introducing the principle of large-scale optical switch array drive and control circuit,a single high speed,amplitude adjustable opti⁃cal switch control circuit is designed first,and then 2000 optical switch array drive and control circuits are designed,and then the selection basis of main chips is given.Finally,the correctness of this design is verified through experiments.By creatively using two digital potentiometers and one high-speed switch,the drive control circuit design with adjustable high level and low power average is realized,which provides a reference for the design of the drive and control circuit of the optical switch array.
